Specific embodiment
The structure and use of the utility model is described in detail in the embodiment provided in below in conjunction with the accompanying drawings.Reference
Attached drawing, this kind have pressure switch (1) and switch enclosure (3) and a pair of of work for the switch of electric therapeutic apparatus control output current
To exchange the 5 core connectors (4) of DIN of electricity output, there is compression spring (2) between pressure switch and switch enclosure, it is characterised in that
5 electric wires for having 5 groups of elastic conducting strips and one of 5 core connectors of DIN inside switch enclosure are connected in parallel, 5 groups of elastic conductings
The other end of electric piece connects a resistance and a contact respectively, and another line of another 5 core connector of DIN and power supply directly connects
It connects.As shown in Figure 1, contact from top to bottom is contact 1 (5) respectively, resistance 1 (6), contact 2 (7), resistance 2 (8), contact
3 (9), resistance 3 (10), contact 4 (11), resistance 4 (12), contact 5 (13), resistance 5 (14).
It is R if resistance 1, resistance 2, resistance 3, resistance 4, the resistance value of resistance 5 are equal below in order to describe conveniently, and
If：R=1000 Ω, line voltage：220V, 50Hz.And according to providing human body in standard GB/T/T 13870.1-2008 tables 1
755~1900 Ω of total impedance under the conditions of 225V, 50Hz, as basic foundation.
When not in use, spring flicks pressure switch, deenergization.When in use, pressure switch (such as floor push)
(1) when depressing (or depressing), the conductor pin of connecting wire is contacted with contact 1 at this point, electricity on (being described below with depressing) switch
Source is formed into a loop by resistance 1.Output current is at this time：I=220V/1000 Ω=0.22 ampere.It is opened if continuing to depress pressure
It closes, the elastic conducting strip of contact 2 and contact 1 contacts at this time, and power supply is formed into a loop by resistance 1 and resistance 2 in parallel, electricity in parallel
It hinders and is：Rz=1000/2=500 Ω.Output current is at this time：I=220/500 Ω=0.44 ampere.It is opened if continuing to depress pressure
It closes, the elastic conducting strip of contact 3 and contact 2 contacts at this time, and power supply is formed back by resistance 1 and resistance 2 in parallel and resistance 3
Road, parallel resistance are：Rz=1000/3 Ω.Output current is at this time：1000 × 3 Ω=0.66 ampere of I=220 ÷.If continue
Pressure switch is depressed, the elastic conducting strip of contact 4 and contact 3 contacts at this time, and power supply is by resistance 1 and resistance 2 in parallel and electricity
Resistance 3 and resistance 4 are formed into a loop, and parallel resistance is：Rz=1000/4=250 Ω.Output current is at this time：I=220/250 Ω=
0.88 ampere.If continuing to depress pressure switch, the elastic conducting strip of contact 5 and contact 4 contacts at this time, and power supply is by electricity in parallel
Resistance 1 and resistance 2 and resistance 3 and resistance 4 and resistance 5 are formed into a loop, and parallel resistance is：Rz=1000/5=200 Ω.It exports at this time
Electric current is：I=220V/200 Ω=1.1 ampere.At this point, under the control of operator, there can be 5 groups of different electric currents defeated
Go out, meet the needs of different electric current tolerance level crowds.It unclamps and rides, pressure switch (1) resets under the effect of recoil of spring power, breaks
Switch power supply.Different depresses dynamics, can obtain different output currents, this output current is according to the 5 groups of resistance used
Impedance or a combination thereof decision.
As long as according to different needs, by resistance 1=R1, resistance 2=R2, resistance 3=R3, resistance 4=R4, resistance 5=
The impedance value of R5 passes through appropriate variation, you can obtains different electric current output.The all-in resistance that 5 groups of contacts all contact calculates public
Formula is：
Rz=R1R2R3R4R5/ (R1R2R3R4+R2R3R4R5+R1R3R4R5+R1R2R3R5).
The all-in resistance formula of remaining 4 groups of contact can be repeated no more according to above-mentioned derivation.
A variety of different all-in resistance combinations can so be obtained, you can the switch of a variety of different electric current outputs of control.
In this way, using 5 power cords in 5 core modular connections of DIN, by the ingenious combination of the present apparatus, achieving can obtain
Obtain the ideal effect of different electric currents output combinations.
